Which explanation of this behavior is true?

Refer to the exhibit.

An engineer must block all traffic from a router to its directly connected subnet 209.165.200.0/24. The engineer applies access control list EGRESS in the outbound direction on the GigabitEthernet0/0 interface of the router. However, the router can still ping hosts on the 209.165.200.0/24 subnet.

Which explanation of this behavior is true?
A . Access control lists that are applied outbound to a router interface do not affect traffic that is sourced from the router
B . Only standard access control lists can block traffic from a source IP address
C . After an access control list is applied to an interface, that interface must be shut and no shut for the access control list to take effect
D . The access control list must contain an explicit deny to block traffic from the router
